You have a very well put together package, that is superior to most other packages, I think the price is were the hobby guys would have think about it, is it cheaper than say Mach plus a Smooth Stepper Plus spindle control
Your package with 125mhz step rate, would do for almost any machine control, that most would need, so a good selling point would be they would not need to buy a Smooth Stepper, or a spindle control board
This would then put your price close to what they would have to spend for all the extra, that your package already has
